All of the jokes that Ari make's at Lloyd's expense are making fun of him for being gay and/or Asian. When Ari wants Lloyd to feel bad about how he handles his job he refers to Lloyd's sex life. Sexual terminology is referrenced often, and has negative connotations in connection to Lloyd. He makes fun of Lloyd for being gay and Asian in nearly every episode of season 6, he also hassles him about his weight. Lloyd always responds well to Ari's insults. He usually just brushes it off and keeps his mind focused on the task he is currently working on. Sometimes, he will even laugh or go along with the abuse.
Not only does Ari constantly yell at Lloyd, but he also talks down to all of his other employees. He makes sexist comments to female coworkers, and he does not listen to anyone else's opinions. There is a lot of pressure in the office because all of the agents are competing for clients against other agencies.
Perhaps the most interesting aspect that comes from this office rhetoric is that fact that there aren't any consequences for Ari's behavior because he is the boss. Ironically, he shows no respect to his coworkers, but expects respect in return.
The rhetoric used by Ari is what makes the show a comedy. Without Ari, there would not be any comedic relief. The show would just be a series of hookups with a movie gig thrown in on occassion. With every one-liner and sexual innuendo, Ari steals the show.
